The current rating of a contact is defined as the current level that creates a certain temperature rise of the contact spring — usually 20°C or 30°C. Both electrical and thermal factors govern the heat created by the current.
The difference between the maximum and minimum temperatures or between the highest and lowest mean temperatures during a specified time interval.
